Portable ultrasonic handheld cutter

Abstract

The invention discloses a portable ultrasonic handheld cutter which is mainly characterized in that a piezoelectric ceramic transducer is connected to a tool head via a 12.9-grade high-strength screw; a nylon washer A is mounted on an upper surface of a front cover zero-vibration point of the piezoelectric ceramic transducer and a nylon washer B is mounted on a lower surface thereof; a transducer middle drum and a transducer upper drum tightly press the nylon washer A and the nylon washer B by means of screw-thread fit; the piezoelectric ceramic transducer is fixed inside a transducer housing, an insulation sleeve B is mounted on the inner side of the transducer middle drum, and an insulation sleeve A is mounted on the surface of a ceramic sheet of the piezoelectric ceramic transducer, so as to prevent electrodes from being connected to metal; a transducer drum rear cover is connected to the transducer middle drum via threads; a vent hole and an aviation-plug wiring opening are formed in the transducer drum rear cover; and the aviation-plug wiring opening is connected to, via a cable, a signal cable connected to an ultrasonic drive power supply. The portable ultrasonic handheld cutter has the advantages of being small in size, light in weight, low in noise, low in energy consumption, convenient and flexible in operation, and wide in application range, and effectively reducing the cost and improving the production efficiency.

Description

technical field [0001] The invention relates to a general-purpose ultrasonic cutting device, which is a portable ultrasonic hand-held cutter, suitable for solving the problem that soft, viscous and brittle materials in the food industry and tough and viscous materials in the rubber industry are difficult to process. Background technique [0002] At present, the existing ultrasonic cutting equipment is mainly composed of ultrasonic driving power supply, piezoelectric ceramic transducer, horn and tool head. The piezoelectric ceramic transducer of this equipment is fixed on the transducer through the interference fit of the pressure ring. In the transducer shell, the working end of the piezoelectric ceramic transducer amplifies and transmits the amplitude through the horn, and acts on the tool head. The piezoelectric ceramic transducer is connected to the ultrasonic drive power supply through the signal cable to drive the piezoelectric ceramic transducer. The device converts el...
